Method and apparatus for obtaining data for a dental component and a physical dental model

Abstract

Methods for obtaining data and for manufacturing a dental component and a physical dental model of at least a part of a dental structure are provided which can improve processing times and provide sufficient manufacturing accuracy. An embodiment of the method can comprise obtaining a first data record for manufacturing the dental component and a second data record for manufacturing the physical dental model. The first data record can comprise data based on a portion of a digital dental model. The second data record can comprise data based on at least the portion of the digital dental model. In this regard, the data upon which the first and second data records are based can be obtained using first and second scanning resolutions in order to improve processing times and provide sufficient accuracy.

AI Technical Summary

Benefits of technology

[0013]US-A-2005 / 0177261 discloses a method for treating teeth, without using a plaster model. The method includes capturing a digital dental model taken directly within an oral cavity to generate data representing the digital dental model. A physical dental model is produced using the data representing the digital dental model and a stereolithography apparatus. The physical dental model is then used as a pattern to manually fabricate a crown and for accuracy check. However, in accordance with at least one of the embodiments disclosed herein is the realization that even if the procedure described in US-A-2005 / 0177261 solves some issues relating to the use of a plaster model, the method does not suggest CAD / CAM production of the crown. In this regard, in accordance with another of the embodiments disclosed herein is the realization that accuracy is provided as the crown is formed directly on the physical dental model.

Problems solved by technology

According to at least one of the embodiments disclosed herein are the realizations that fabrication of the study cast can be relatively time consuming and cumbersome.

It is also inconvenient and sticky to handle the plaster.

Furthermore, it can be cumbersome and time consuming to mount the study cast in the articulator.

Also, the curing process of plaster can be difficult to control.

However, in accordance with at least one of the embodiments disclosed herein is the realization that even if the procedure described in US-A-2005 / 0177261 solves some issues relating to the use of a plaster model, the method does not suggest CAD / CAM production of the crown.
